Southard, can you expand a bit on the application of the internal wind pressure?
We mount the panels with at least a foot of open space below them, and they're only about 4 feet high at the top. Wind speeds will be equalized to a great degree.
The ultimate expression of this would be a...
This is a fantastic thread guys!
dcarr, one of the ways I checked the number from the tool was to compare with the structural strength of the panels. They're rated at 113 psf, which implies that wind loads on the panel would generally be less than that (well, maybe). Thus when I got back a...
Thanks again Adam.
Not to sound completely dense, but is my calculation of approximate loads correct? IE, its just p times "real" area, as it is in 6.5.15? Or should it be the real width times L, the projected length?
BTW, 6-21 could be used as a limit check. Panels are roughly h/D = 1, so if...
Wow, thanks for the replies guys, this is almost real time!
Avak: That -0.3 was my typo *sigh*
dcarr: I'd prefer to use C&C because it's easier to work with IMHO (everything's in one table). But I was told the numbers came from MFRD, and the numbers he put in the notes show CN's that seem to...
We're using Windloadcalc and a similar spreadsheet to calculate the lift forces due to wind loading on a solar array. Both tools use ASCE 7-05 Section 6.5.13 for "open" buildings, which seems to be widely accepted as the proper methodology for rooftop tilted solar arrays. When we type in similar...
